Uhm. I was gonna say, “It’s a pelican. It’s brown. Could it be a Brown Pelican?” But I figured that’d be too easy, and it’s some sort of escaped exotic or something. Although I don’t know of any other pelican species with overall brown colouration.

Nice shot! Lovely lighting, good blurry background that looks quite nautical, which is always important for a typical picture of this species. The only thing that could make it better is if were standing on a pier post.
